HALIFAX, Nova Scotia (June 30, 2006) - EnCana Corporation (TSX, NYSE: ECA) and the province of Nova Scotia have reached an Offshore Strategic Energy Agreement (OSEA) that establishes the framework for the potential development of the Deep Panuke natural gas field located about 250 kilometres southeast of Halifax, off Canada's East Coast.

"This is a very good first step in restarting the development of the Deep Panuke gas field. We are pleased to have established a framework with the province for royalties, employment and industrial benefits, plus funding for research and education. However, we have plenty more work to do to make Deep Panuke production a reality. For Deep Panuke to go forward, it will take the constructive efforts of all parties involved as we seek regulatory approval, tender the work and consider this major investment decision," said Dave Kopperson, EnCana's Vice-President, Atlantic Canada.

Over the past three years, EnCana has continued to assess Deep Panuke's resource potential as it developed a new plan to make the project as economic as possible. A key component of that work is the OSEA, which outlines commitments to provide specific industrial and employment opportunities in Nova Scotia, plus establishes a royalty framework that clarifies the opportunity for the owners to earn a fair return, and for Nova Scotia to generate substantial economic activity and benefits. As a next step, EnCana is preparing to file a Deep Panuke project description this summer with the Canadian Environmental Assessment Agency and a development plan application later this year with the Canada-Nova Scotia Offshore Petroleum Board. Details on the project's estimated size, reserves, production volumes, schedule, facilities and capital cost are expected to be included in the regulatory applications. Bringing Deep Panuke to reality requires a timely and favourable review of the regulatory application, attractive market conditions and funding approval by the EnCana Board of Directors, a decision that may be considered by the end of 2007.

EnCana Corporation
With an enterprise value of approximately US$50 billion, EnCana is one of North America's leading natural gas producers, is among the largest holders of gas and oil resource lands onshore North America and is a technical and cost leader in the in-situ recovery of oilsands bitumen. EnCana delivers predictable, reliable, profitable growth from its portfolio of long-life resource plays situated in Canada and the United States. Contained in unconventional reservoirs, resource plays are large contiguous accumulations of hydrocarbons, located in thick or areally extensive deposits, that typically have lower geological and commercial development risk, lower average decline rates and very long producing lives compared to conventional plays. The application of technology to unlock the huge resource potential of these plays typically results in continuous increases in production and reserves and decreases in costs over multiple decades of resource play life.
